Source code (including specifications or data that can be used
as source code equivilants) are dual licenced under the above license, or
the following simple permissive license:

Redistribution and use in source and compiled forms, with or without

These license terms does not apply to the content of https://joeyh.name/pics/
which is content aggregated from elsewhere, or to pages that are
aggregating RSS etc feeds from elsewhere.

Note that the above is written to appease people who feel that the copyright
regime must be taken seriously when it comes to things posted on the internet
for the express purpose of being viewed by others on the internet.

I don't subscribe to that viewpoint myself. I do enjoy the legal hack of
copyleft licenses, as applied to free software. But, when it comes to basic
human communications online, such as this website, I prefer to consider
reality:

To get from my server to your screen, these very words have been copied and
re-copied dozens and dozens of times, and have been broken apart, modified,
reassembled, used as inputs for complicated processes that produced derivative
works and combined them with other inputs licensed under other, possibly
conflicting licenses. This happens no matter what license anything is under.
It's how networks and computers work.

If you don't like that, you shouldn't post your stuff online. If you post your
stuff online and think some license can prevent such things, think again.
I love it. Copy away!
